CAST-STEEL UNDERFRAME FOR CARS.

Specification of Letters Patent. Patented Sept. 17, 1912. Application filed June 16, 1911. Serial No. 633,621.

To all whom it may concern:

Be it known that I, CLARENCE H. HoWARD, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Cast-Steel Underframesfor Cars, of which thefollowing is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 is a top plan view Fig.2 is a longitudinal sectional View on the line 22; Fig. 3 is a cross sectional View on line 3-3, Fig. 1; Fig. 4 is a cross-sectional view on lined-4, Fig. 1, and Fig. 5 is a sectional ,view on line 5-5, Fig. 1.

This invention relates to a new and useful improvement in cast steel underframes for locomotive tenders and other railway rolling stock, the object being to construct a cast steel frame for use in connection with cylindrical tanks.

In the drawings, 1 indicates the longitudinal members and 2 the bolster members, these latter, as shown in Fig. 1, being concave to accommodate the cylindricaltank and being provided with center plates and side bearlngs, as shown. The upper curved member 3 of the bolster is strengthened by 7 preferably four parallel vertical webs 4 connected by top and bottom'flanges, the extremities of these top flanges being braced by the vertical webs of the longitudinal members, beyond which are strengthening webs 5. Openings are arranged in the top and bottom plates to support the cores in 1 position during the process of molding. The

upper flanges of the longitudinal members 1 are flared outwardly and upwardly in the plane of the top flanges at the ends of the bolster member, as shown.

6 is the front end sill whose ends are braced by diagonal bracket extensions 7 extending from the longitudinal members, the pocket 8 for the coupler in this instance being above the plane of the bottom flanges of the longitudinal members and reinforced'by horizontal webs and radial strengthening webs 14 as shown, there being two lateral pockets 8 to accommodate the safety chains.

The rear end sill 9 has its ends braced by diagonal members 10. i

11 is a housing for the draft rigging which extends between the longitudinal members The side walls and is not liableto be broken in service. It

may readily-be molded, and, as the parts are all cast integral, the absence of fastening devices prevents the parts from becoming loose.

I claim:

1. In a cast steel underframe the combination of longitudinal members having top and bottom flanges extending upwardly and outwardly, a bolster, member having a curved top plate coincident with said top flanges and a bottom plate coincident with said bottom flanges, said bolster member having webs connected at their ends to said longitudinal members and length to said top and bottom plates.

2. In an underframe having longitudinal draft members a bolster member comprising a curved top plate, a bottom plate, transversely disposed webs connecting said top and bottom plates, said top and bottom plates having 0 enings therein'between said webs, and longitudinal members whose verthroughout their tical webs are connected to the ends of said transversely disposed webs.

3. In an underframe having longitudinal draft members, a bolster comprising upper and lower plates secured at their extremities to the draft members, said upper plate being concave and said lower plate being shaped to form a center. bearing.

4. In an underframe having longitudinal draft members, a bolster comprising upper and lower plates connected at their extremities to the draft members, transverse webs connecting said upper and lower plates and secured at their extremities to the draft members, said plates being provided with series of openings intermediate said webs.

5. An underframe having longitudinal draft members provided with upper and lower flanges; and a bolster comprising an upper plate connected at its extremities with v the upper flanges of the draft members, a lower plate connected at its extremities with the lower flanges of the draft members, vertical webs connecting said upper and lower plates, said plates being provided with series of openings intermediate said webs.

6. An underframe having longitudinal draft members provided with upper and lower flanges; and a bolster having a concave upper plate connected at its extremities to the upper flanges of said draft members, and a lower plate connected at its extremities to the lower flanges of said draft members, said lower plate being shaped to form a center bearing.

7. In an underframe having longitudinal draft members composed of vertical webs and horizontal flanges, a bolster comprising webs connected at their ends to the webs of the draft members, and upper and lower plates connected at their extremities to the flanges of the draft members and to the transverse webs throughout the length of said transverse webs.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses, this 13th day of June, 1911;
